Blackberry Pie

I started here:

But, (as usual) I made some substitutions.  Not that this pie needs any, as I've tasted the original.  Here it is anyway:

1/2 of the flour was whole wheat
2 T. cornstarch vs. 1.5T
1/2 t. ground cloves vs. 1 t. cinnamon
and finally, blackberries instead of apples


Verdict: Mmmm!
